DAC+DSP + HifiBerry OS not starting up

I have a Raspberry 1B in combination with the new DAC+DSP, connected via ethernet.

Tried the Hifyberry OS, this did not start-up, no ethernet connection. Than tried Beocreate, that worked , SSH, system configuration, however Spotify showed up in spottily however no connection could be made....

So, what would you recommend as a proper SW that will work in combination with Spotify and the DAC+DSP.
